Rosemary holds the honor of having the largest breast measurements of any Playboy Playmate in history.

According to The Playmate Book, Rosemarie was discovered by Playboy through unusual means–she needed an interview with a millionaire for the college newspaper she was writing for, so she traveled to the United States and went to the Playboy Mansion in Chicago where, through pure gumption, she got Hugh Hefner on the record. During the interview, he asked her if she would be interested in becoming a Playmate.

She has had quite a career including serving as a magistrate in England and now running a public relations firm from her home in N. Wales.
